The speed test dont show ping

The app is nice for a baseline but it does have its issues. 

1. it doesn't always choose the fastest server and you can't switch servers. 

2. it doesn't show ping. 

I'd highly recommend testing using a hardwired in pc if you want the best/detailed results. 

Please post about this in the Orbi app forum:

Good Luck.
